4 Claims.

This invention has to do with air handling apparatus andfis'more specically concerned with a inountingifor` a window ventilator applicable tov an ordinary'. window such as occurs in the average dwelling house. It is a general objectof the present invention to provide a simple, neat and effectivestructure readily applicable to. an ordinary window.l

Most dwellingy houses are constructed with windows. ofthe. type ordinarily known as double hung windows, this: type` of .window being characterized` by a. window" frame withztwoy spaced, vertical guideways' each' offwhich carries a sash in'which thereis a paneyof glass. A sill isl proe vided at thebottom of the case immediatelyffor.- ward of: the.. innermostguideway. Myy present invention isI primarily concerned with air han-f dling apparatus applicable to a window ofthe type just referred to and it is a general object ofthe invention to provide aunit that: can-.be readily; applied to such a window so that it'. is; mounted securely. is sightly in appearance, and that'. does not rmar` or mutilate any part of the window con.- struction,.eitherfthe frame or the window sash;

A further: objectv of my presentinventionV is to provide a;V Verysimpleinexpensive construction wherebyA a box-like body; carrying ay fan orz-any airghandling apparatus. is mounted in a window. to reston thersilland to. have a lip that bears forward on thesilland a lip that` bears;rearward on the glass carrying window sash tothe end that the-bodyY is firmly supported and. is maintained tightly inposition, mainly by virtueoi its own weight, while themajor portiono thefbodyprojects from theV sash; atl the. exterior of the structurein which the window occurs.

Another object'of my invention is. to provide a simple, improved construction whereby.` the unit that I have'provided can be readily. accommodated to windows of'various widths.

The various objectsand. featureseof my invern tion will beV fully understood from the following detailed description of a typical preferred form and application of. the invention, throughout which description reference is made to the accompanying drawings, in which:

Fig. 1. is aV front elevation of the structure provided by my invention showing it applied to a typical double hung window. Fig. 2 is an-r enlarged vertical sectional view of the window structure showing the unit that I have provided in place. therein and showing, parts broken away-to appear in section. Fig. 3 is a plan- View of the unit that I have providedV showing it inplace. in thewindow.

2 My present invention is primarily. concernedwith a unitor.-devicefapplicableto a.doub1e.hu.ng window andinfthefdrawings I have shown such a window structure; In accordance; with: concimon co.nstruction.A the Window involves, generallyia frame A4 and a pair: of.g1ass;carrying-.sashes IB- carried by the frame. The frarne involves, gem. erally, vertical sides .lilandabottom or ledge l2. Thesides `I 0 have spaced opposed panels or.. guilde-V ways !lthat carry thesashesandat thefbottom of the frame. there isasi1l-I3f-that ploiectsabove the. .ledge -l Land proj ectsasuitable distance for.- wardfromv the innermost guideway. The windowsash. Bv; is` a simple rectangular. frame, usually;`

. formed of wood. carryingla.A pane oglassl.. In

the drawings Ihave shown` only. the lower portion of theinnermost sash Blsince my construction is designedV to cooperatewith thisI particular. part` ofthe window. Theinner. sasl1.B.of.the window.. as shown in. thev drawings, includes a lower cross member.. lli; and VVerticalside...mem.- bers l1 whichr slide-inthe vinner-most i. guidewayV l 4.- The, structure that. I have.. provided includes., generally, a body C which`v is a. box-.like struc? ture andf. which. is provided.. or formed, with. few simple. parts to facilitate. its. application to, a. window constructed. as. aboven describedl The i body. is. generaly, a .casing `or housingcarr-ying or accommodating air handling. or, treating; equipment.. For instance, it may house a motor driven fan F or it. may include or, carry lter, pads or other equipment, as desired. Soiar as my present inventionis concerned it, willv sulce to point outthatthebody hasatop 2,.a.bottom 2l., sides ZZanda back. 23. The body further includesa front.panel..2.4.which is of special construction as provided by my, invention.. In the particular. case illustrated the sidesZZ andbackl. are of louvered formation. while the.v top, bottom, and sideshave, inwardly turnedanges 26.to. which the front panelmay be attachedso that the body. forms a complete,v assembled unit, boxflike in character. It is tov be understood that. in .practice. anysuitable means. may be. used to. join the variousparts.ofthebody and the elements of. the.v body that. I have referreditocanbe either integrally joinedi or made. separable. as circurn7 stances require.

In accordance. with my inventionv thev front panel124f faces into the.. roomI or faces-inwardly Whenthe structurels in positionin. a. windows andthereforeit is finished part, neat and sightly in, appearance. The frontpanel in. thecase i1.- lustratedhas a central. opening 30V to pass. air and this opening is provided; inV arasedsecton 3 3|. The panel 24 is also shown as provided with embossed parts or ribs 32 which extend horizontally and enhance the appearance of the structure. I provide the lower edge portion of the front 24 with a rearwardly or outwardly projectbl ing ange 35 which extends horizontally and is such as to rest upon the window sill I3. The projecting edge portion of the flange 35 is provided with a depending lip 36 which extends down behind the sill I3. The top edge portion of the front 24 is provided with a rearwardly or outwardly projecting flange 3l of substantially the same extent as the flange 35 which flange 31 terminates in an upwardly projecting lip 38 which, when the device is in use, bears against the front side 39 of the sash member I6.

At each vertical edge of the front 24 there is a rearwardly or outwardly extending flange 40 similar to the flanges 35 and 3l and the flanges 40 preferably terminate in laterally projecting ears 4|.

I apply the structure that I have thus provided to a common or typical double hung window construction of the type described by simply resting the flange 35 on the sill I3 so that the lip 36 engages behind or against the outer edge of the sill, and I lower the window sash B so that the sash member I6 closely approaches or bears on the top 20 of the body C while the lip 38 bears outwardly against the face 39 of member I6. With the parts in this position, as shown in Fig. 2, the body projects outwardly in the window opening and may extend a substantial distance out beyond the structure in which the window occurs. The action of gravity on the body causes it to tend to turn in a manner to keep the lip 36 tight against the sill I3 while the lip 38 is maintained tight against the sash member I6.

I may, in practice, make the body that I have described of a width to properly fit the particular window in which the device is to be used. However, ordinarily I make the body somewhat narrower than the window opening and pro vide filler plates 5U at each side of the body to extend from the body to the sides of the window frame. Each filler plate 50 may be a simple flat plate cut wide enough to occupy the space between the body C and the side of the window frame, it; being preferred to proportion each filler plate so that it engages behind an ear 4I and extends into a channel I4 in the frame and to make it long enough so that it coincides in vertical extent with the front 24 of the body. In practice I may make the ller plates 50 simple fiat plates and depend on Wedging them or pressing them tightly into position. However, I prefer to make them secure, as by turning a flange 60 on each plate 50 to seat in the bottom of the innermost channel I4 of the frame and the flanges 60 may be made secure in the case by nails 6I or other fastening means.

In carrying out my invention I prefer to form the front 24, the several flanges in connection therewith, the lips and ears above described, as a single integral or continuous part, for intance, I prefer to make these elements as a single stamping, as shown throughout the drawings.

Having described only a typical preferred form and application of my invention, I do not wish to be limited or restricted to the specific details herein set forth, but wish to reserve to myself any variations or modications that may appear to those skilled in the art and fall within the scope of the following claims.
